The Top Six Benefits of Data Modeling – What Is Data Modeling?
Understanding the benefits of data modeling is more important than ever.
Data modeling is the process of creating a data model to communicate data requirements, documenting data structures and entity types.
It serves as a visual guide in designing and deploying databases with high-quality data sources as part of application development.
Data modeling has been used for decades to help organizations define and categorize their data, establishing standards and rules so it can be consumed and then used by information systems. Today, data modeling is a cost-effective and efficient way to manage and govern massive volumes of data, aligning data assets with the business functions they serve.
You can automatically generate data models and database designs to increase efficiency and reduce errors to make the lives or your data modelers – and other stakeholders – much more productive.

What Is a Data Model?
A data model is a visual representation of data elements and the relationships between them. Data models help business and technical resources collaborate in the design of information systems and the databases that power them. They show what data is required and how it needs to be structured to support various business processes.
There are three types of data models: conceptual, logical and physical, and each has its own purpose defined primarily by the level of operational detail. With each stage of data modeling, the data model becomes more information- and context-rich.
A conceptual data model is a rough draft, containing the relevant concepts or entities and the relationships between them.
A logical data model, also referred to as information modeling, is the second stage of data modeling. It is a graphical representation of the information requirements for a given business area.
A physical data model provides the database-specific context, elaborating on the conceptual and logical models produced prior. Accordingly, physical data models are often treated as the blueprint for a proposed database.
Why Is Data Modeling Important?
Although data modeling isn’t new, it is becoming an increasingly important practice because of the large amount of data organizations are tasked with processing and storing.
A good analogy is that of a house and its architect. The architect designs a house with with the end user/occupant in mind. It has to be constructed with right functionality in the right places.
So think of a table of data as a room in the house. But in the context of data management, the house doesn’t have just 10 rooms – it has 10,000, each with varying degrees of interconnectivity and importance to the organization.
At this scale, oversight can be catastrophic. Therefore, the visual representation provided by a data model gives organizations the confidence to design their proposed systems and take them live.
Data modeling is a critical component of metadata management, data governance and data intelligence. It provides an integrated view of conceptual, logical and physical data models to help business and IT stakeholders understand data structures and their meaning.
Quite simply, you can’t manage what you can’t see.
Top Six Benefits of Data Modeling
Data modeling is the first step to ensuring mission-critical information is used, understood and trusted across the enterprise. It has many benefits. Following are the top six benefits of data modeling organizations can realize:
- Improve discovery, standardization and documentation of data sources.
- Successfully design and implement databases.
- Support regulatory compliance now and into the future by governing data modeling teams, processes, portfolios and lifecycles.
- Empower employees by enabling self-service data access and foster collaboration by improving inter-departmental/IT and business alignment.
- Improve business intelligence and make it easier to identify new opportunities by expanding data capability, literacy and accountability across the enterprise.
- Encourage more cohesive integrations of existing information systems as new systems are implemented with a greater perspective of the organization’s current state.
